v4 V I Patented Aug. 9, 1949 r entreemess Pi rre-Ne "orrics PIPE JOINT James W. Simpson, Decatur, Ill., assignor to Mueller 00., Decatur, 111., a corporation of Illi-' nois Application April 13, 1945, Serial No. 588,097
1 Claim. (01. 285-105) The present invention relates to corporation stops and method of installing the same and has as its purpose to provide for the installation without the necessity of equipping the stop and the main opening in which it is to be secured with the customary inter-engaging threads. In threading openings in mains made of Transite or similar plastic materials, taps quickly become dulled and, consequently, the present invention is applicable to particular advantages in the case of such mains, although not limited to such use. An installation in accordance with the invention is shown in the accompanying drawing, in which Figure 1 shows a portion of a main in transverse section, and, partly in longitudinal section and partly in elevation a'stop at a certain installation stage, and
Figure 2 is a view similar to that of Figure 1, showing the stop in a different installation stage.
The stop comprises anelongated body 5 provided with a longitudinal flow passage 6 intersected by a conical valve seat in which is engaged a conical valve plug 1. One end of the body is provided with threads 8 whereby the stop is adapted to be coupled to a service line.
The other end of the body is provided with a threaded portion 9 adjacent the plug and outwardly of the threaded portion with a neck portion II] which is externally smooth. The ex tremity of the neck portion is bevelled at H and inwardly of the bevel is an external circumferential groove I2.
Engaged with the threaded portion 9 is a follower nut I3 for a gasket M which preferably frictionally engages the threads so as to be retained against droppingwhen the stop is suspended with the neck portion down. Reference numeral I5 designates a resilient split metal ring disposed in the groove l2 and having a normal diameter such that it projects outwardly of the groove, as shown in Figure 1. The ring has a flat top surface and a lower bevelled surface It which extends in to the lower edge of the groove.
Assuming that the main, designated at 11, contains a fluid under pressure, a drilling machine such for example as is shown in the patent to F. H. Mueller et al., No. 2,196,651, Sept. 22, 1942,
-is applied to the main and an opening l8 of slightly larger diameter than the neck portion Ill is drilled. The drill is then removed from the boring bar and replaced by a stop inserting tool such for example as is shown in patent to F. H. Mueller et al., No. 2,247,427, July 1, 1941, and the tool is engaged with the threads 8 of the closed stop. The boring bar is then lowered through .the drilling machine barrel to insert the neck portion in the opening l8, being guided into the latter by the bevelled surface ll. As the stop is lowered, the bevelled surface [6 of ring [5 engages the top edge of the main opening so that as a result of the camming action the ring is contracted, as shown in Figure 2, so as to be able to pass through the opening. Nut I3 is so positioned on the threaded portion for abutment by the gasket l 4 that somewhat before ring I 5 clears the lower edge of the opening l8, the gasket will engage the top margin of the opening so as to be compressed by the time the ring clears the lower edge of the opening to expand to the locking relation shown in Figure 1. The operator pulls up on the boring bar to make sure that the ring has expanded to locking position and, if it has, he rotates the boring bar to release the tool from the stop, whereupon the drilling machine can be dismounted.
The compression of the gasket by the inserting operation thus described produces two results, (1) a seal is provided between the stop and the main, and (2) the stop is held against any tendency to rotate with the tool as the latter is being turned 011. However, full compression of the gasket will not ordinarily be obtained during the inserting operation and after the drilling machine has been removed nut I3 is threaded downwardly to compress the gasket to the desired degree. The follower nut and gasket here shown follow the disclosure of the patent to J. W. Simpson, No. 2,265,703, December 9, 1941.
In the case of a main of plastic material, the tightening of nut l3 causes the sharp upper edge of ring l5 to bite into the lower margin of opening l8 to provide a secure seating, ring l5 being sufficiently powerful so that it will not be appreciably contracted by the upward pull, even in the case of the usual cast iron or steel main.
Variations in the form and arrangements of parts are contemplated as possible without dement means.
JAMES W. SIMPSON.
